A derogatory term used on 4chan's /lgbt/ board to refer to a subtype of nonpassing trans women who transitioned later in life, typically baby boomers. Boomerhons are (stereotypically) generally either autogynephilic or sissy fetishists and come across as caricatures of women on account of being oblivious to how they are perceived.
